My present invention relates to matter disclosed in 'my co-p'endingapplications Serial Nos. 671,109 and 703,237 filed May 15, 1933 andDecember 20, 1933, respectively, and is a division '5 of the latterapplication.

A principal object of my invention is to pro vide improved means for-making shoes of the type originally taught in my United States PatentNo. 1,569,823, wherein an insole. to which the upper is aflixed,includes an integral heel portion, a shank portion, and a ball portionhaving a central opening therein defining a continuous marginal randextending from the front of one side of the shank around-the toe and .tothe front of .the opposite side of the shank to afford means forinitially afiixing the upper to the insole, and an outsole is providedhaving a marginal depression conforming to the rand for receiving thesame with'the upper attached thereto, whereby the central portion 'ofthe inner face of the outsole is disposedfiush with the upper surface ofthe rand.

A further principal object is to provide means for producing an outsoleand a complementary insole therefor, whereby the insole and outsoleportions of the shoe are patterned and sized at the same time from asingle piece of sole material to insure that the insole and outsoleportions are of relatively proper shapes and sizes.

A further object is to provide a combination pattern and cutting die forrounding the outsole and initially forming an insole for use therewith.Other and further objects will appear from the following specification.

Referring to the drawings: I

Figure 19 is a sectional view taken on line 19--19 of Figure 18. g

In carrying out my present invention I prefer to first incise the solematerial to define an insole portion of suitable size, thickness andproportions, and then to round the outsole from the same piece ofmaterial in relation to the insole thus defined.

To accomplish thisI may employ a pattern or template, as shown in-Figure 1, which com prises a body portion 20 and side and end portions21 and'21, between which I removably secure thin and flexible cuttingblades 22-22 by means of countersunk screws 2323 .etc. The

' is reenforced by a perforate backing strip 36.

(See Figure 11) which is formed to'complement the depressed portion ofthe sole and is preferblades22 are positiori edland arranged to extendoutwardly from the face of the pattern a distance corresponding to thethickness of the insole to be provided "and are contoured in conformitywith the sole portion of the last on which the shoe is to be assembled.

As indicated in'the drawings, it is usually not necessary that the fulloutline of" the insole be incised in the sole material or that theblades 22 extend to accomplish that purpose inasmuch as the insoleordinarily conforms in size and shape to the outsole over the shank andforward portions of the heel and may be formed with the outsole in thesole rounding operation here after to be described. 1

In all other respects the pattern is of the usual type heretoforeemployed and is provided with holes therethru at 24 and 24 to receivethe positioning pins 25-25 of a conventional sole rounding machine,fragmental supporting parts of which are indicated at 26 in Figures 2and 3. l When the pattern has been positioned on the sole roundingmachine, a piece of sole material 27, of uniform thickness, is laid overthe pattern and rests upon the cutting edges of the blades 22, whereuponthe clamp 28 of the rounding machine is forced down upon 'the material,causing the blades 22 to cut into the material and firmly holding thematerial against the face of the pattern during the rounding operationperformed by the knife 29, as indicated in Figures 1 and 2. The roundedsole 30 is then taken from the machine and appears with incisionstherein as indicated at 3232 in Figures 4 and 5.v

'As illustrated in Figure 3, the blades 22 may be made to extend fromboth faces of the pattern so that alternate faces thereof may beemployed to form the'sole portions of a mated pair of shoes.

Although I have found the foregoing method of producing the, rounded andincised sole 30 economical and otherwise of advantage, itwill beunderstood that the sole as it appears in Figures 4 and may be providedin other ways than that above described for the purposes of carrying outthe further operationsof my improved method, and that the sole may firstbe rounded and subsequently incised to define the insole portion ifdesired.

a shoe, and that waste marginal portions corresponding to the materiallying outside of the incisions and within the depth thereof will alsoresult.

[Before performing such splitting operation however, I prefer to inflexor depress the central ball tread portion of the rounded and incisedsole 30 to a distance somewhat greater than the depth of the incisions32. This I accomplish by pressing the sole between the male and femaleelements, 33 and 34 respectively, of a swage or pressing die, asillustrated in Figure 7.

After removal from the pressing die, the sole ably made of a durable andsomewhat flexible composition material. The sole thus backed up is thenpassed between the rolle rs 37 -37 of a conventional leather splittingmachine, the splitting blade -38 of which positioned to cut within thedepth of the, incisions 32 and above the bottom of the depressed area35, so that when the sole has been split its-full length, an insoleportion 39, perforate centrally of its ball tread portion, and anoutsole portion 40, is provided. Waste marginal portions 41 also resultfrom this operation, as will be readily understood.

The insole 39, formed as above, comprises an integral heel portion, ashank portion and a ball portion, the said ball portion having a centralopening therein defining a continuous marginal rand. 39' extending fromthe front of one side of the shank around the toe and to the front ofthe opposite side of the shank.

The insole 39 is next lasted to the upper 42 of the shoe to which it issecured byany of such special adhesives as are well-known in this art,or by other suitable means, preliminary to which a patch 43 may beremovably pasted to cover the perforate portion of the insole.

Theoutsole 40 is then. placed in position over the lasted insole and thedepressed portion 35 thereof is forced back into itsoriginal normaldisposed flush with the upper surface of the' rand. l a

The remainingsteps necessary to complete the shoe are the usual onesconsisting in removing the patch 43, assembling the sole lining 50 andaffixing a heel 51. Since the disclosure of the foregoing in mycopending application No. 671,109 filed May 15, 1933, I have madevaluable improvements in my original method which are disclosed in my-copending application Serial No. 703,237 filed .December 20, 1933, andthe improvements in means which are particularly illustrated inFigures.16 to 19 hereof.

I have found that a plate 60 may be removably substituted for the clamp28 of-the sole rounding'machine; that a pattern or template 61 may besubstituted for'the; pattern 20; and'that the parts 60and 61 may beformed so as to depress the central area 35 of the ball portion of thethan the thickness of the insole to be split therefrom. By providing theelevated areas and depressed areas on opposite faces of the partsBil-61, respectively, I am enabled to use the same parts'for patterning.and depressing soles for mated pairs of shoes by merely inverting theplate 60 and pattern 61 in the sole rounding machine.

It will be understood that the sole material 27 is clamped underpressure in the sole rounding machine between the plate 60 and pattern61,

thereby inflexing the sole material over the central area of the ballportion of the sole to be rounded, .and that the sole is then rounded inthe machine by the blade 29 guided by the side edges of the pattern.

7 The sole thus formed and rounded may then be reinforced by theperforate backing strip 36 and split in the leather splitting machineabove the bottom of its depressed area 35 to provide a rounded outsoleand a perforate insole of lesser thickness and equal area.

I have further found that, in the operation of clamping the solematerial in the rounding machine, I may also define and initially forman insole of suitable size, smaller than the outsole, by making a plate(Figure 18) of a shape and size correspondingto the insole desired andproviding it with a double edged blade 22'. The blade 22' is secured byscrews'23' to the plate at the margins thereof and extendsperpendicularly from the unelevated face portions of the plate adistance corresponding to the thickness of the insole to be 'formed. Inthis manner the plate 60' is used to incise the sole material in muchthe same manner as the pattern 20 is employed, as heretofore described.

When the plate 60, carrying the blade 22', and the pattern61 are usedtogether, the sole material is infiexed over the area 35 thereof and theincisions 32 are cut therein to define an insole. all in the act ofclamping the sole material in the rounding machine. Subsequently, when.vthe sole-has been rounded and split above the depressed area 35 andwithin the depth of the incisions 32, as previously set forth, theoutsole portion 40 and complementary perforate insole portion 39 result.Thereafter, the upper may be amxed to the insoleand the outsoleassembled thereto as above described to provide a finished shoe..

In this manner, I have provided a very simple and inexpensive method andmeans for producing my improved complementary outsole and insole memberswithout adding to the number of operations ordinarily necessaryfor-their production, and with the further advantages of minimized wasteand insured perfection of sizing. a

Many modifications in the method and means J here taught will becomeapparent from this disclosure to those skilled in the art to which thisinvention relates'and I desire, therefore. to have-the foregoingconsidered merely illustrative of my invention as defined in the hereappended claims which are restricted tomy speciflc means, the method andimprovements therein being claimed in. my copending applications abovereferred to.
